SQLite3 & AGUP list trouble
Raf Vermeulen

I'm quite stuck (again::)). I want to read in all records from an SQLite3 table and show them in a list (the type you can select something in). This's the example code: 

char *lister(int index, int *list_size) {
    static char items[10][32] = {"box", "text", "input", "button", "menu",
       "selection", "slider", "scrollbar", "list", "window"};
    if (index >= 0) {
        return items[index];
    }
    else {
        index = 10;
        *list_size = index;
    }

    return NULL;
}

The problems start to arise as soon as I want to change the 10 to the amount of records. I've got to remove the static then, which gets other parts to complain (especially either assigning a string like "test" to it, or in the return items[index] or due to the function's return type). Anybody here able to put me in the right direction? Thanks in advance.

I don't understand what the above code bit has anything to do with either SQLite3 or AGUP. I also can't understand the words below the code.

That's part of the example code from AGUP, which creates the contents of a list-box. The words underneath basically mean that it got me to fiddle 'round and 'round to get it to work. It currently got me to this:

1char *lister(int index, int *list_size) {
2 int records;
3 records = count_records();
4
5 int open_dbase;
6 const char *zErrMsg = 0;
7 int result;
8 sqlite3_stmt *stmt = NULL;
9 
10 char *items[records][(LENGTH + 1) * MAX_BYTES_PER_CHAR];
11
12 for(int i = 1; i <= records; i++) {
13 items<i>[(LENGTH + 1) * MAX_BYTES_PER_CHAR] = "Test test";
14 cout << "Item: " << items<i>[(LENGTH + 1) * MAX_BYTES_PER_CHAR] << "\n";
15 }
16 
17 if (index >= 0) {
18 return items[index][(LENGTH + 1) * MAX_BYTES_PER_CHAR];
19 }
20 else {
21 index = 10;
22 *list_size = index;
23 }
24 
25 return NULL;
26}

It works fine, and the cout comes on, but then the whole program crashes. The function's called in this code:

1int show_dbase() {
2 int count = count_records();
3 char sel2[count];
4 
5 DIALOG show_dlg[] =
6 {
7 /* (dialog proc) (x) (y) (w) (h) (fg)(bg) (key) (flags) (d1) (d2) (dp) (dp2) (dp3) */
8
9 /* this element just clears the screen, therefore it should come before the others */
10 { d_agup_clear_proc, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL, NULL, NULL },
11 
12 // Show records
13 { d_agup_list_proc, 40, 25, 200, 150, 0, 0, 0, 0, 0, 0, (void*)lister, 0, 0 },
14 { d_agup_push_proc, 90, 180, 100, 18, 0, 0, 0, 0, 0, 0, (void*)"Back", 0, (void*)closebutton },
15 { d_agup_push_proc, 275, 10, 10, 18, 0, 0, 0, 0, 0, 0, (void*)"?", 0, (void*)about },
16 
17 /* the next two elements don't draw anything */
18 { d_yield_proc, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL, NULL, NULL },
19 { NULL, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, NULL, NULL, NULL }
20 };
21 
22 set_gui(show_dlg);
23
24 
25 return D_REDRAW;
26
27}
